Title: Operating mechanism for travelling crane drive - has force feedback to crane operating lever proportional to travel speed
Inventor: DANIELI STEN HENRIK DIPL ING
IPC: B66C13/56
Filed: 1975-12-24
Abstract: The operating mechanism is intended for a travelling crane drive and has a switching lever or similar held in a neutral position by springs and connected so that the crane travel speed depends on the position of this level when it deviates from its neutral position. The lever n2) is fixed to a spindle that, due to a force feedback element experiences a resistance to rotation proportional to the magnitude of the current being supplied to the crane drive motor or proportional to acceleration. The current to the motor is determined by potentiometers with the arms coupled to the spindle. The advantage lies in giving the crane driver a 'feel' for the speed at which it is travelling.

Title: Demonstration measurement device for sinusoidal signals - is for continuously variable frequency enabling instantaneous voltage measurement
Inventor: SIEGMUELLER ALFRED
IPC: G01R1/02
Filed: 1976-01-08
Abstract: A demonstration measurement device is designed to electrically sense a measurement signal by continuously scanning its phase so that the instantaneous voltage at each phase point can be measured with a direct voltage instrument. The sensing process converts the measured signal in an output signal of any low frequency including zero Hertz, and is thus suitable for use with sinusoidal measurement signals of any continuously selectable frequency. A revolution counter on the device records the measurement values recorded by the device. for each setting of the counter the measurement value from the device agrees with the simultaneously recorded value from the counter. The device uses a pulse generator producing a pulse at a defined point of rotation of a shaft which is continuously manually variable.

Title: Sync. linear motor with stationary windings - incorporates DC transmission and local inverters of modular form
Inventor: WEH HERBERT PROF DR ING
IPC: B60L13/00
Filed: 1978-02-16
Abstract: The synchronous linear motor control system design is modified by replacing the AC power transmission to the individual stationary windings with a DC system. The necessary inversion is carried out locally at each winding by an inverter of modular form. The DC transmission eliminates inductive losses and interference in the connections. The local modular construction gives units of less power than the centralised inverter of the original design. This enables the use of bipolar high power transistors which gives a simplification of the inverter controls.
